7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are considered as starting values which should be shortened or ex-
tended as appropriate. Particularly harsh applications or heavy duty operation, such as
high dust loads in the environment or in the process gas, other contamination or ingress
of process material, can make it necessary to shorten the maintenance intervals signifi-
cantly.

Monthly
• Check for abnormal noise, see
• Check for excessive vibration, see Operating Condi-
tions.
• Check the operating liquid temperature, see Operat-
ing Liquid Connection.
• Check the machine for liquid leaks - in case of leaks
have the machine repaired (contact Busch).
If applicable check gland packing leakage rate (20 to 40
drips per minute) and adjust as required.
Every 2500 operating hours
• Regrease the bearings. The amount of grease ac-
counts for 2/3 of the free space of the bearing cham-
ber.
• Check the tension on the v-belt (if applicable).
